Decision tree for choosing VR system

Wondering which VR system will suit your needs best ?

The selection is rather abundant these days. The better known ones are:
Acer, Daydream, Dell Visor, Gear VR, HP, HTC Vive & Vie Pro, Lenovo Explorer, Oculus Go & Rift, Mirage Solo, PSVR and Samsung Odyssey.

If you wanted to compare each of them to each other, you would end up with 78 comparison pairs.

Comparison tables can look quite intimidating too!

Is there a quick and painless route ?

This article will help you to evaluate all the major devices without breaking a sweat.

The whole process is laid out as a decision tree. At each stage you will make a selection narrowing down the available choices.

All devices are arranged in groups which share certain key characteristics. Each stage of a decision tree is constructed as a list of major pros & cons comparing one group against the other.

You simply work your way down the tree until you end up with a handful of devices. At this point some minor differences and current price deals will help you make a final call.

Let’s go !

Please read from the start to go through the entire decision tree. Links peppered throughout the text will let you skip the sections which are not applicable in your case.

Is it worth the price ?



There are a couple of things you should be aware of before you even start.

First of all: motion sickness (if you know all about it then press here to skip).

To cut a long story short – it is likely that initially, VR will make you sick. It takes some time and patience to develop “VR legs”.

You shouldn’t start with a fast paced dog-fight and try to force yourself through it. This may result in a retch every time you try VR again, not to mention a few stains on the carpet.

Start with something slow where you can stand still and just interact with the environment.


The second thing to remember is the risk of VR headaches (skip – don’t !)

Once you put your hands on a headset you shouldn’t cut corners with adjustments, especially with respect to IPD. Without doing this correctly, you may end up in a wonderland where proportions between your body and other objects are weird. This tends to result in nasty headaches.

You can measure your IPD using a mirror and a ruler or a webcam. Just remember that if it is above the 67 mm range, any software correction in most cases won’t be good enough and you should consider getting a headset with a hardware adjustment mechanism.


The third thing to bear in mind is a problem of accommodating your glasses (yawn – skip).

In general VR headsets are more comfortable without glasses. The level of comfort when you use them varies from headset to headset between good and problematic.

For some systems you can get a correction insert which you mount inside the headset.

Other than that, if your giant goggles are too huge to fit into the headset, maybe you should think about contact lenses.

That’s health & safety covered.



Let’s start with the cheapest products (a serious gamer ? – then skip).

The cheapest is probably Google cardboard. To use it you will need a suitable smartphone. There are a bunch of other options (notably: Gear VR and Daydream) which require a smartphone as well.

All these headsets simply allow you to attach your phone to your head and use it as a screen and a hardware platform for games and other experiences.

The biggest flaw of these devices is a lack of positional tracking.

Other major limits are discussed here.



If you plan to use VR a lot, you should consider standalone VR headsets (die-hard gamer ? – then skip).

Oculus Go and Mirage Solo require neither a smartphone nor any other additional hardware. They work on their own (there are more devices of this type coming up e.g. Vive Focus, Oculus Santa Cruz).

Oculus Go lacks positional tracking so if you are fine with that you should investigate further. At this point I won’t evaluate it in more details.

Mirage Solo provides positional tracking but only for the headset. Controllers feature only orientation tracking. Just like with Oculus Go, I don’t cover this in more detail at the moment.



The best VR experience you can get is delivered by devices powered either by PlayStation 4 or a PC (take me straight to the very best).

Neither of them are cheap (a few hundred for the headset alone), so you should consider these only if you are a serious gamer, that is, someone who plays at least a couple of hours every week.

Even though these devices are top of the line, they share some shortcomings. You need to be aware of them before you proceed.



Let’s decide if you should get a VR system for PlayStation 4 or a PC.

Pros of PSVR:

  • the price of PlayStation 4 is at least two times lower than any VR capable PC
    Note: PSVR requires PlayStation 4, other systems rely on a PC.
  • there are no problems with using any content for PSVR
    In theory any VR game for a PC can be used with any VR system for this platform. In practise you may run into problems if the game was not tested/created for the system you happen to have.
  • no software conflicts
    At times you’ll find that on a PC, after you install the required software, there is a chance that it won’t work properly because of the conflicts with other programs.
  • no hardware compatibility issues
    For a PC, some pieces of hardware are notorious for turning people gray – particularly USB 3.0. Out of all the VR systems for PC, only Vive doesn’t use this version of the port (note that Vive Pro does).
  • Aim Controller
    It is an excellent “gun” for PSVR. On a PC, there is a tracker for the Vive which could be attached to a “gun” or anything else for that matter. Currently however, there is not much you can do with it.
  • the headset accommodates glasses well
  • more living room friendly than a PC

 

Cons of PSVR in comparison with PC VR:

  • less content
    There is a decent amount, just not as much as for a PC.
  • the price of the PSVR (excluding PlayStation 4) is in the same price range as cheaper VR systems for a PC (excluding a PC itself of course)
    Sometimes there are special offers which make PC VR cheaper, however, the total cost i.e. PSVR headset + camera + controllers + PS4 is lower than any PC VR system + suitable PC.
  • not possible to make the headset wireless
  • impossible to use for work
    PC programs with a VR interface can actually be used to create something. There aren’t many of them though.
  • impossible to use VorpX to play non-VR games in VR
  • no integrated headphones
    A minor issue since only the more expensive PC systems have it
  • no hardware adjustment to IPD
    A minor issue since PSVR software adjustment works up to 70 mm

 

If the pros in your evaluation overwhelm the cons, you have a choice – PSVR. If you have some questions about it, please take a look at this list and you may find the answer.

In case cons are not acceptable please read on.



Let’s compare Windows Mixed Reality (WMR) with other systems for a PC.

Windows Mixed Reality: Samsung Odyssey, Lenovo Explorer, Dell Visor, Acer and HP.

Other systems: Oculus Rift, HTC Vive & Vive Pro.

Pros of WMR:

  • better screen resolution
    Only Vive Pro beats the majority of WMRs and matches Samsung Odyssey however, it is more expensive than any of them.
  • the play area is limited only by the length of the cable (~4m)
  • easier to use once everything is installed and configured
    WMRs do not require any additional auxiliary equipment like sensors, base stations etc. All they need is a PC.
  • minimal hardware requirements which are less demanding
    WMRs work with certain graphics cards which are integrated into the processor so you don’t need to buy a graphics card at all. That comes at a cost – the display framerate is 60Hz instead of 90 recommended for top quality VR experience. Of course you can upgrade your system later.

 

Cons:

  • tracking of the controllers is somewhat limited
    When they are out of field of view of the cameras installed in the headset or too close to them, tracking becomes erratic. It is not bad, just annoying for some games.
  • no official VorpX support
    That may change in the future.
  • playing Oculus exclusives is usually possible, yet may not be as good as on the Oculus Rift itself
    That’s mostly due to the fact that Oculus Touch controllers are the best at the moment. As a side note it’s worth noting that the Oculus Store is widely credited as the best content provider.
  • the fit between the face and the visor (front part of the headset) may be too loose
    Other headsets are built as goggles so they sit on your face as tight as you choose. As a result they won’t wobble when you shake your head.
  • currently no option to make the headset wireless

 

If cons win, click here. Otherwise please read on.



Let’s choose which WMR system is for you.

Samsung Odyssey vs other WMRs.

Pros of Samsung Odyssey:

  • hardware adjustment to IPD
    Software adjustment for other WMRs has an upper limit of 67 mm.
  • quality headphones and microphone integrated with the headset
    That’s more convenient than using the external ones.

 

Cons in comparison with other WMRs:

  • more expensive

 

If pros shine, you have made a choice: Samsung Odyssey – congratulations 😎

If you prefer a cheaper WMR than Samsung, Lenovo Explorer seems to be the next best choice.

It’s light, very comfortable and has a wide field of view.

Other WMRs are not bad at all and are worth considering if the price is right.



Let’s evaluate Vives and Oculus Rift.

Pros of both Vives (Vive and Vive Pro) vs the Rift:

  • better fit for glasses
    You can adjust the eye relief for the headset which creates more space for glasses.
  • bigger play area
    If you don’t have a spare area of 11 ft x 11 ft (3.5 m x 3.5 m), this advantage is useless.
  • brighter screen
  • Vive Tracker
    There are no trackers for Oculus. There is not much you can do with the Vive Tracker at the moment though.

 

Pros of the Vive Pro vs Vive & Rift:

 

Pros of the Vive vs Rift & Vive Pro:

  • doesn’t need troublesome USB 3.0

 

Cons of both Vives vs the Rift:

  • too much sweating may damage Vive and Vive Pro
    There are problems with having it fixed under warranty.
  • both are more expensive
    Vive Pro is significantly more expensive than the Vive.
  • experience on a weak PC may not be as good as on the Rift
    Oculus asynchronous spacewarp technology compensate for sudden frame rate drops, which are more likely on a less capable PC.

If cons feel more significant, choose the Rift.

Otherwise, using pros specific for the Vive and Vive Pro and remembering that Pro is more expensive, you can narrow down your choice to a single device.

Bear in mind that Vive Pro is compatible with Base Station 1.0 and 2.0. Vive will only work with 1.0.

Thanks to TPCAST adapter it is possible to make Vive and Oculus headsets wireless. It is not the easiest thing to use though and it is quite expensive.

Vive is releasing its own wireless adapter very soon. It is to be seen how good it is.

If you have more questions about the Rift or Vive, you may be able to find the answers here and here respectively.



The best VR systems at this point are: HTC Vive Pro and Samsung Odyssey. They have the highest resolution and a wide field of view.

Bear in mind that Oculus Touch (the native controllers of the Oculus Rift) are still king of the hill.

Pros of the Vive Pro:

  • tracking of the controllers is accurate everywhere in the play area
    Tracking of the Odyssey Controllers has some blind spots. Most games work good enough, however occasional glitches may be annoying, especially when rock solid tracking is a must.
  • very soon it will be possible to make the headset wireless using Vive’s wireless adapter
  • Vive Tracker
    The tracker can be attached to any object to make it part of the game. There is not much you can do with it at the moment.
  • adjustment of the eye relief
    That’s useful for making more space for glasses if you need them.

 

Cons of the Vive Pro:

  • too much sweating can damage the headset
    Having it fixed under warranty can be a problem.
  • inferior audio quality
  • more expensive
  • more demanding system requirements
    Samsung delivers 60 Hz frame rate when run on a weak PC. 90 Hz is a minimum for optimal VR comfort. Of course you can always buy a monster graphics card later.
  • less portable
    Samsung Odyssey doesn’t require any external sensors.

 

Pros win – choose the Vive Pro. Otherwise the Samsung Odyssey is a better choice.



Is it worth the price ?

To answer this question, it is helpful to put the price in perspective. Click the system you chose to go to the relevant section: PSVR, Oculus Rift, HTC Vive. If you decided to grab WMR or Vive Pro, the reasoning for HTC Vive holds in these cases as well.

    Well done decision tree. A few comments about Odyssey vs Vive Pro. The Odyssey has better lenses with the best black levels. I thought the Vive Pro was going to have better sound but they botched it. But the biggest advantage of the Odyssey is the ability to enable Motion Reprojection (ASW)–it’s awesome. SweViver says Motion ReProjection makes the Odyssey a better choice than the Vive Pro.

    Motion Reprojection for WMR and ASW for Oculus are a significant plus over the Vive
